1) put the phone down = put down the phone
2) put a baby down = put down a baby.
3) put an amendment down = put down an amendment.
Does the preposition 'down' in those phrasal verbs have a flexible position around the object?
If not, why not?

As user 5jj posted on usingenglish.com...
Unfortunately for learners, there are many different types of what are loosely called 'phrasal verbs'.
He identifies Verb + Preposition, Verb + particle, Prepositional Verb, Phrasal Verb, Intransitive verbs followed by a particle/adverb, and Intransitive phrasal verbs as the 6 main subtypes, each with different constraints on how they can be validly used.
But probably the main constraint for most constructions called "phrasal verbs" is that if there's an object, and if that object is expressed as a pronoun, it must appear between the verb and the preposition. Thus...
She told him off (valid idiomatic phrasal verb meaning She rebuked him)
She told off him (not a valid construction)
By my definition of "phrasal verb", OP's examples #1 and #3 simply aren't (they're just ordinary "literal" usages). The true phrasal verb put down has two possible primary senses...
Mary put down the old dog (she either denigrated or euthanized it)
She put it down (valid phrasal verb as above, or the literal sense placed [in a lower position])
She put down it (never valid)
The compound particle can often change its place before or after an object.
Up to now I haven't found the rule that defines exactly when the changing is possible. I think only with some very frequent particles.
In some cases this changing of place is not possible. Modern dictionaries indicate when the particle can change place with a special sign.

I've just consulted the Longman grammar by Alexander to see what he says. The grammar point is treated in section 8.28 and I see that is quite a tricky problem.
